Application led July 16, 1967. Serial No. 384,284.

To all whom it may concern:

Be it known that I, IRA BOYD, a citizen of the United States, residing at Pond Hill, in the county of Luzerne and State of Pennsylvania, have invented a new and useful Ice-Shaping Machine, of which the following is a specification. f

The invention relates to an ice shaping machine.

The object of the present invention is to provide a simple, inexpensive and efficient ice shaping machine of great strength and durability, adapted to cut pieces of ice into cakes of the desired size, and thereby avoid the waste. resulting from carrying up in an elevator the broken ice, which is afterward thrown out at the ice house.

lVith these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed. out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacriicing any of the advantages of the invention.

In the drawings Figure 1 is a side elevation of an ice shaping machine, constructed in accordance with this invention. Fig. 2 is a plan view of the same. Fig. 3 is a central longitudinal sectional view. Fig. al. is a transverse sectional View, taken substantially on the line -QJ of Fig. 1. Fig. 5 is a similar view, taken substantially on the line y-g/ of Fig. 1.

Like numerals of reference designatel cor-` responding parts 1n all the figures of the` drawings.

1 designates the frame of the machine, designed to be constructed of any suitable material and provided with a longitudinal opening or passage-way 2 for the pieces of ice to be cut into cakes of the desired size. The frame is provided with a horizontal bottom 3, and the piece of ice to `be cut into cakes is moved along the same by means of rotary feeding devices, which may consist of spur wheels 4 or other suitable means.

The spur wheels 4, which are located at opposite sides of the frame, extend into the same to engage a cake of ice at opposite sides thereof, and they are mounted on vertical shafts 5, which are journaled in suitable bearings of upper and lower resilient arms 6, arranged in pairs at opposite sides of the machine and secured at one end to the same. The arms 6, which are constructed of suitable resilient material, are provided between their ends with quarter bends 7 to arrange their attached ends in vertical planes and their free ends in horizontal planes, the attached ends being fitted flatwise against the frame, as shown.

The short vertical shafts 5 carry pulleys 8, which are connected by belts 9 with pulleys 10 of the vertical shafts 11, extending from the top to the bottom of the frame and connected with a horizontal line shaft 12. Instead, however, of employing a belt and pulley for communicating motion from the long vertical shafts 11 to the short vertical shaft 5, sprocket, or any other form of gearing, which will not interfere with the lateral movement of the feed wheels, may be employed. The yieldably mounted laterally adjustable feed wheels are adapted to move inwardly and outwardly in a direction transversely of the frame to yield to the inequalities of the side faces or edges of a piece'of ice.

The frame of the machine is provided at opposite sides with upper and lower bearings 13 for the vertical shafts 11, and the latter extend above the frame of the machine and have grooved pulleys 15 fixed to them. The grooved pulleys receive transverse belts 16, which consist of cables and which are also arranged upon a double pulley 17, having a pair of grooves to receive the belts 16. The line shaft, which is journaled in suitable bearings 18 of the frame of the inachine, is located above the frame and extends along the same being centrally arranged, as clearly illustrated in Fig. 2 of the drawings. Instead of employing belts and pulleys for communicating motion from the longitudinal shaft 12 to the vertical shafts 11, any other form of gearing may be substituted for the belts and pulleys to communicate motion from the longitudinal shaft to the vertical shafts 11. The longitudinal shaft is provided with a driven pulley 19, and when it is rotated in the direction of the arrow in Fig. Q of the drawings, the transverse belts will move in the direction of the arrows, and both of the feed wheels will be rotated to feed'a blockof ice forwardly through the machine. The driven pulley 19 may be connected by a belt with any suitable motive power, and the latter may be also connected with the machine in any other preferred manner. lIhe line shaft is extended in advance of the front end of the fra-Ine, and hung therefrom is an oscillavtory saw-carrying frame 20, which swings transverselyof the machine andy which is also slidable longitudinally of the same along the line shaft to cut the ice as the same is fed forwardly by the mechanism heretofore described. The oscillatory saw-carrying frame, which is located in advance of the frame of the machine, is provided with parallel sides between which are mounted upper and lower pulleys 21 and 22, which are connected by a belt 23, but any other preferred form of gearing may be employed for communicating motion from the line shaft 12 to a pair of spaced circular saws 24, which are mounted at the lower end of Y the oscillatory frame upon a shaft 25. The

circular saws 24 are located between the sides vof the frame and are keyed to the shaft 25 to f of the oscillatoryframe along such shaft.A

The saw-carry1ng frame is adapted to swing across the path of the ice, and it is provided with a rod A28, having a suitable handle 29 and adapted to enable the operator to push or pull the saw-carrying frame to secure the desired rapidity of the cutting operation and to complete the same. When the oscillatory saw-carrying frame is swung to either side of the machine, it is adapted to swing automatically therefrom to the center, and during such movement, the cutting operation will be entirely automatic. The saw-carrying frame is moved longitudinally of the line shaft by means of a lever 29a, fulcrumed at an intermediate point on the frame of the machine at one side thereof and having upper and lower arms, the upperarm being provided with a forked head 30 to straddle the line shaft and engage the inner `or rear side of the oscillatory frame. -The upper arm is also bent laterally and extends inwardly to arrange the forked head centrally of the machine. The lower arm 31 of the lever 29 is inclined and is arranged to be engaged by the right hand feed wheel, which is provided with spokes 32 and arranged to engage the lower arm 31 of the lever, whereby as the vice is fed forwardly, the oscillatory frame will bemoved outwardly. This will relieve the circular saws of strain and enable them to cut freely and rapidly. The lower arm of the lever is released by the spokes 32 yat the completion of the cutting operation, and the oscillatory frame is moved rearwardly by a coiledA uadapted tomake two cuts into av block *orV l piece of ice, and they may be spaced apart af sufficient distance to cut the ice Yinto cakes y of the desired size. A single saw, however, can be'employed, and the oscillatory frame may be held to one side while the ice is being fed forwardly to arrange the desired cut of the ice in advance of the saw. The saws may be of sufficient diameter to cut entirely through the ice, or a kerf may be made of sufficient depth to enable the ice to be readily broken. The coiled spring 33, which isdisposed on the outer portion of the longitudinal shaft, is interposed between the front or outer side of the oscillatory frame and a pulley 34. The top of the ice is trimmed Vby a horizontally arranged reciprocatable'saw 35, extending across the machine at the front thereof and carried by a pair of vertical crank shafts 36 and 37, havingV intermediate crank bends 38, arranged in suitable eyes 39 of the saw. The vertical crank shafts are journaled in suitable bearings of the forwardly extending arms 40, and they are pro- Y vided adjacent to the arms with adjustable collars 41, adapted to permit the crank shafts to be raised and lowered to position the horizontal reciprocatable saw properly with relation to the ice for trimming the cakes to the desired size. The crank shaft 37 is extended at the top and is provided witha pulley Y42, which is connected by a belt 43 with the pulley 34, whereby motion is communicated from the line shaft to the crank'` f shaft 37. hen the crank shaft'37V is ro- 10o tated, the saw will be reciprocated by 4the cranks, which will move in unison. The crank shafts may, however, be connected by a suitable gearing, and .any other form of gearing maybe employed for connecting the crank shaft 37 with the line shaft.
